摘　　要：为了解常见绿化树种叶片的含硫量,在乌鲁木齐市选择工业区、道路交通区、生活区和公园游憩区等4种功能区,观测大气SO_(2)和10种主要树种叶片的硫含量,比较不同功能区大气SO_(2)和叶片硫含量的差异。结果表明:乌鲁木齐大气SO_(2)含量平均为0.021 g·m^(-3),公园游憩区、生活区、道路交通区和工业区分别为0.009、0.013、0.030和0.036 g·m^(-3)。灌木叶片硫含量(2.91 mg·g^(-1))高于乔木(2.47 mg·g^(-1));10种树种叶片硫含量依次表现为榆树>刺槐>榆叶梅>皂荚>山桃>山楂>紫叶李>丁香>白蜡>火炬树。生活区、道路交通区及工业区与公园游憩区的相差百分比为-17.8%~29.1%、27.2%~147.9%和37.5%~222.1%,相差百分比最小的树种分别是火炬树、榆树和皂荚,最大的是山楂和紫叶李;道路交通区、工业区与生活区相差百分比为10.1%~111.1%和32.0%~149.7%,相差百分比最小的分别是山桃和皂荚,最大的是山楂;工业区与道路交通区相差百分比为5.5%~100.0%。皂荚、紫叶李、白蜡、火炬树、榆叶梅和丁香叶片硫含量与大气SO_(2)含量为显著线性关系(P<0.05)。The sulfur dioxide content in the atmosphere and the sulfur content in the leaves of ten main greening tree species were measured in four functional areas,including industrial areas,traffic areas,residential areas,and park areas of Urumqi.The differences between the sulfur dioxide content in the atmosphere and the sulfur content in the leaves of different functional areas were compared.The results showed as follows:the average sulfur dioxide content in the atmosphere of Urumqi was 0.022g·m^(-3)and that in park areas,residential areas,traffic areas,and industrial areas was 0.009g·m^(-3),0.013g·m^(-3),0.030g·m^(-3),and 0.036g·m^(-3),respectively;the sulfur content in the leaves of shrubs(2.91mg·g^(-1))was higher than arbors(2.47mg·g^(-1));the sulfur contents in leaves of ten tree species were in the following order:Ulmus pumila>Robinia pseudoacacia>Amygdalus triloba>Gleditsia sinensis>Amygdalus davidiana>Crataegi pinnatifidae>Prunus cerasifera f.atropurea>Syringa reticulata var.amurensis>Fraxinus chinensis>Rhus typhina;the percentage differences among recreational areas,traffic areas,industrial areas and park areas were 17.8%-29.1%,27.2%-47.9%and 37.5%-222.1%,respectively,of which the smallest were Rhus typhina,Ulmus pumila and Gleditsia sinensis,and the largest were Crataegi pinnatifidae and Prunus cerasiferaf.atropurea;the percentage differences among traffic areas,industrial areas and recreational areas were 10.1%-111.1%and 32.0%-149.7%,respectively,of which the smallest were Amygdalus davidiana and Gleditsia sinensis,and the largest was Crataegi pinnatifidae;the percentage differences between industrial areas and traffic areas were 5.5%-100.0%.The sulfur contents in the leaves of Gleditsia sinensis,Prunus cerasiferaf.atropurea,Fraxinus chinensis,Rhus typhina,Amygdalus triloba,Syringa reticulata var.amurensis were significantly linearly correlated with the atmospheric sulfur dioxide content.
